109 G-14 was very similar as 109 G-6, the main difference was water methanol boost system with G14. I skinned our MT-507 as Bf 109 G-14, here is part of my info text:
"Most of people call this plane from the Tikkakoski Aerial Museum as Bf 109 G-6, but actually it is Bf 109 G-14 without the water-methanol injection system. It also has the same canopy type than G-14 and in it's original factory delivery document it has been identified as "Bf 109 G-14 Jabo Rei". 
The G-14 was basically a late-war Bf 109G-6 with some parts (e.g. the tailfin) made of wood because of the shortage of strategic materials, especially aluminium. 
It also had a FuG 16Z radio with which the G-14s were delivered. So it is very  close to a G-14. One could call it as a G-14 since many G-14s lacked the MW-50  aswell due to production problems anyway. This would give finns a 109G which would  have an Erla-haube since the new G-6 model is modeled with the heavy frame canopy." 
It is in the game, now.
